The Crown of Thorns at Notre Dame Cathedral in Paris. The relics of the Passion presented at Notre-Dame de Paris include a piece of the Cross along with the Holy Crown of Thorns, and of all the relics at the Notre Dame de Paris Cathedral, the Crown of Thorns is without a doubt the most precious and the most revered.
My crown of thorns has developed some problems over the past several months. As background, I received the plant from my mom about 7 years ago (she's had it for about 20 years). I think it has bloomed, maybe, 3 or 4 times since I've had it.
